Abstract
The utility model discloses a lightweight light diffusion plate. The lightweight light diffusion plate comprises a light diffusion plate material with light transmission, wherein the light diffusion plate material with light transmission is formed with a plurality of tiny bubbles or air holes used for improving the optical performance thereof and decreasing the density thereof, the bubbles or the air holes are fully distributed in the light diffusion plate material, and the density of the light diffusion plate material selected to be 0.4 to 0.7 g/cm<3>. The lightweight light diffusion plate disclosed by the utility model is better in optical performance, lower in density, lighter in weight, and lower in cost.
Description
Technical field
The utility model relates to diffuser plate technical field, especially relates to a kind of light-duty light diffusing sheet.
Background technology
In prior art, light diffusing sheet is widely used in various display screens, and light diffusing sheet is the clear sheet being formed out by expressing technique or Shooting Technique, light diffusing sheet is heavier, increase the weight of display screen, also increase the cost of light diffusing sheet, be therefore necessary to be improved.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of light-duty light diffusing sheet, and its optical property is better, and density is less, and weight is lighter, and cost is lower.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of light-duty light diffusing sheet, comprise the light diffusing sheet sheet material with light transmission, the light diffusing sheet sheet material of light transmission forms some for submitting its optical property to and reducing small bubble or the pore of its density by foam process, bubble or pore are covered with light diffusing sheet sheet material, and the density of light diffusing sheet sheet material is chosen for 0.4～0.7g/cm
3.
Further, in technical scheme, two surface formings of described light diffusing sheet sheet material have optical grains protrusion or depression.
Further, in technical scheme, two surface formings of described light diffusing sheet sheet material have optics frosted trace protrusion or depression.
Further, in technical scheme, the density of described light diffusing sheet sheet material is chosen for 0.4～0.5g/cm
3, 0.5～0.6g/cm
3or 0.6～0.7g/cm
3.
Further, in technical scheme, the density of described light diffusing sheet sheet material is chosen for 0.4g/cm
3, 0.5g/cm
3, 0.6g/cm
3or 0.7g/cm
3.
Adopt after said structure, the advantage that compared to the prior art the utility model had is: light diffusing sheet of the present utility model has better optical property, and meanwhile, its density is less, and in the light diffusing sheet material of same volume, its weight is lighter, and cost is lower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, light diffusing sheet sheet material 2, bubble or pore.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, as shown in Figure 1: a kind of light-duty light diffusing sheet, comprise the light diffusing sheet sheet material 1 with light transmission, the light diffusing sheet sheet material 1 of light transmission forms some for submitting its optical property to and reducing small bubble or the pore 2 of its density by foam process, bubble or pore are covered with light diffusing sheet sheet material 1, and the density of light diffusing sheet sheet material 1 is chosen for 0.4～0.7g/cm
3.
Two surface formings of light diffusing sheet sheet material 1 have optical grains protrusion or depression.In other embodiment, two surface formings of light diffusing sheet sheet material 1 have optics frosted trace protrusion or depression.
Light diffusing sheet sheet material 1 can be chosen different density, makes product have corresponding optical property and weight requirement, and for example, light diffusing sheet sheet material 1 is chosen for 0.4～0.5g/cm
3, 0.5～0.6g/cm
3or 0.6～0.7g/cm
3.Or the density of light diffusing sheet sheet material 1 is chosen for 0.4g/cm
3, 0.5g/cm
3, 0.6g/cm
3or 0.7g/cm
3.
Light diffusing sheet sheet material 1 is that one or more plastic pellet and the auxiliary material such as azobisformamide in PC, PET, PE, PMMA, PS and PP is uniformly mixed, form main material, wherein to account for the weight ratio of main material be 1～10 ‰ to the auxiliary material such as azobisformamide.
Light diffusing sheet of the present utility model has better optical property, and meanwhile, its density is less, and in the light diffusing sheet material of same volume, its weight is lighter, and cost is lower.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
